To all whom it may concer/1,

Be it known that I, LEON TRAGER, ya citizen of the UnitedStates, residing at Newark, county of Essex, and State of New Jersey have invented certain new :and useful Improvements in Deformable Spacers, fully described and represented inthe following specification and the accompanying drawings, forming a part ofthe same.

This invention relates to an yimproved deformable safety device or spacer'which may be advantageously used with any sectional casing enclosing a pressure or vacuum space, such as steam or gas chambers, liquid chamL bers liable tov freezing, flanged pipe joints, safety valve casings, and thelike, and it is the particular aim of the invention to provide a deformable spacing member having the characteristics of suiiicient resiliency to absorblight sudden shocks without being deformed beyond the limit of elasticity, but which, when forced beyond the limit of elasticity by excessive pressures, which would ordinarily cause rupture of the casing or the like, will bend or take a permanent set so as to permit `separation of the casing or like parts to enable tliepassagey of fluid to or from the casing. yThe spacer preferably will be of such form` as totpermit of the casing joint being thereafter closed by merely tightening up the clamping devices comprising bolts or the like7 and thus enable such spacers to be used two or more times after they have been thus deformed beyond the point of elasticity.

In the accompanying drawingsy forming a partof this specification, the invention is illustrated in modified forms as applied to the flanges of the sectional casing or Chamber in which a pressure fluid may be confined, and the invention will now be de scribed in detail in connection with said drawings and the novel features thereof then be specifically pointed out in the claims.

In the drawings- Figures 1 and 2 are, respectively, a detail end view and a. view looking` to` the left in Fig. 1;

Figures 3 and 4 are, respectively, a side and top view of a modied construction.

Referring now to the drawings, and particularly to Figs. 1 and 2, the spacershown comprises a horizontal torsion member 1,

ecs.`

ed to y'engage a clamping ydevice shown as a bolt ,C which passes through the membery 5 with ther headof the bolt arranged tofcontact with 4the toi l ofthe member 5a large clearance being provided around the shank of the bolt to'prevent it binding onr the member 5 inthe operation ofthe device hereafter described.k The bol-t is threaded into the lower casing fiange B to draw the casing sections together. 4 n y v f In Figs. 3 and 4, the torsion member lcarries heads 6 and bolt-engaging members?, thus doing away` with the lugv 2` and its sea-ting cavity 3. f .i

From the'r foregoing itwill be obvious that when the sections of the pressure chamT ber are forced apart byexcessivepressure therein, the casingsections, and flanges B in separating will produceva- .twisting or torsional bending action. ofthe torsion membery y1, due to the pressure of the bolt.

heads on Athe offset members 5 or 7, as: the case maybe.

yThe spacers are preferably made yof; eX l truded ory drop forged Abrass and tliede formable members 1 are of such resiliency and strength as to yield slightly under sudden slight shocks and react to return the parts to normal position. On excessive pressures, however, which otherwise would rupture the casing, the torsion members 1 are twisted beyond the limit of their elasticity and take a permanent set with the casing parts separated. rl`he form of the members 1 and 4, of Figs. l and 2, and land 7, of Figs. 3 and 4, is such that, o-n subsidence of the pressure causing separation of the casing parts, the bolts C may be tightened to closethe parts of the casing together on the spacers, and the constructions may be used a secondtime, or until theflimit of movement of the parts is reached.

It will be understood that the inventionr is not limitedto the exact form or constructhese maybe modifiedL widely within the tion 'of any of the devices shown, but that ,105'

invention as defined by the claims, and that sures 'tending to separate the casing parts,

said spacer being of such resiliency as to be torsionally deformed beyond its elastic limit and take a permanent set With the casing parts separated on excessive pressure Within said casing.

k2.' Thecombination with a sectional casing and the means for securing the casing parts together, of a resilient spacer supporting the pressure of said securing means and torsionally deformable under excessive pressures tending to separate the parts of the casing, said spacer being of such resiliency as to be torsionally deformed Within its elastic limit'under light sudden shocks and return theV parts v to normal position but to be deformed beyond the'elast-ic limit and take a permanent set With the casing parts separated on excessive pressure Within said casing. 3. The combination with a sectional casing andthe bolts for securing the casing parts together, of resilient spacers for supporting the pressures of 'said bolts and torsionally deformable under excessive pressures tending to separate the parts of the casing', said spacers being of such resiliency as tov be torsionally deformed Within their elastic limits under light sudden shocks and return the casing parts to normal position but to be torsionally deformed beyond the elastic limit and take a permanent set with the casing parts separated When the pressure Within said casing becomes excessive.

4. The combination With a sectional casing and clamping bolts therefor, of resilient spacers for supporting the pressures of said bolts and torsionally deformable under excessive pressures tending to separate the parts of the casing, said spacers being of such resiliency as to be torsionally deformed Within their elastic limits under sudden 'light shocks and return the casing parts to normal position but to be torsionally deformedbeyond the elastic limit and take a permanent set With the casing parts separated'When the pressure Within said casing becomes excessive, said spacers being formed to permit further torsional deformation after the casing parts have been tightened by the bolts after subsidence of such excessive pressure, whereby the spacers may be used a plurality of times.

' 5. A yielding spacer, comprising a member arranged to engage a clampingkdevice, and a torsion device coacting With said member arranged to support the clamping pressure of said clamping device, said torsion device being arranged to take a permanent set when bent under excessive pressure.

6. A yielding spacer, comprising a member arranged to engage a clamping` device,

and a torsion device coacting With said mem? ber arranged to support the clamping pressure yof said clamping device, 4said torsion device having sufficient resiliency to bend and react under light sudden shocks and to be deformed beyond its elastic limit and take a permanent set under continued excessive pressure.

In testimony whereof, I have hereunto set my hand.
